Abstract
The utility model relates to a high-strength drill bit used for drilling, which comprises a hollow cylindrical steel body, wherein bit matrixes are arranged at the bottom of the cylindrical steel body at equal intervals; steps are arranged at the bottom of each bit matrix; a through hole is formed in the lower part of the bit matrix; the high-strength drill bit further comprises strengthening ribs; each strengthening rib penetrates through the through hole in the lower part of the corresponding bit matrix; a plurality of alloy blocks are positioned and mounted on the inner side of the bit matrix and the outer side of the bit matrix. According to the high-strength drill bit used for drilling, the structure is compact and reasonable; the manufacture is convenient; as bit matrixes are arranged at equal intervals and the strengthening ribs are mounted among bit matrixes, the strength of the drill bit is improved, the service life of the drill bit is prolonged, and the work efficiency is improved.
Description
Technical field
The utility model relates to geological prospecting equipment technical field, especially a kind of probing high strength drill bit.
Background technology
Probing is an important technical in geological prospecting work.With rig, from earth's surface, creep into downwards, in stratum, form cylindrical bore, to differentiate and to divide stratum.Can be from boring different depth obtain rock core, sample ore, soil sample and analyze and research, in order to measure physics, mechanical property and the index of rock and soil layer, provide design needs.Rig used is mainly divided into two kinds of swinging and impact types.
In prior art, probing adopts flat-bottom structure with drill bit, and drill bit, in drilling process, when running into hard bottom, easily damages, and its intensity is low, has brought inconvenience to boring work, and application life is short, affects probing work.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of probing rational in infrastructure high strength drill bit, thereby has improved the intensity of drill bit, extends the application life of drill bit.
The technical scheme that the utility model adopts is as follows:
A kind of probing high strength drill bit, comprise into hollow cylindrical steel body, described cylindrical steel body bottom even is arranged at intervals with bit matrix, the bottom of single bit matrix is provided with step, the bottom of single bit matrix has through hole, also comprise reinforcing rib, described reinforcing rib is through the through hole of each bit matrix bottom; The inner side and the outside that are positioned at each bit matrix are all provided with a plurality of alloy blocks.
Further improvement as technique scheme:
Described bit matrix is welded in the bottom of cylindrical steel body.
Described cylindrical steel body bottom even is arranged at intervals with 12 bit matrixes.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, reasonable, easy to make by even spaced bit matrix, and is provided with reinforcing rib between each bit matrix, effectively raises the intensity of drill bit, extends drilling life of bit, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, cylindrical steel body; 2, alloy block; 3, reinforcing rib; 4, bit matrix; 5, step.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, the probing of the present embodiment high strength drill bit, comprise into hollow cylindrical steel body 1, cylindrical steel body 1 bottom even is arranged at intervals with bit matrix 4, the bottom of single bit matrix 4 is provided with step 5, the bottom of single bit matrix 4 has through hole, also comprises reinforcing rib 3, and reinforcing rib 3 is through the through hole of each bit matrix 4 bottom; The inner side and the outside that are positioned at each bit matrix 4 are all provided with a plurality of alloy blocks 2.The design of alloy block 2 has improved the intensity of drill bit.
In actual use procedure, by being evenly arranged at intervals with bit matrix 4, not fragile when drill bit creeps into, formidable opponent is high, long service life, and drilling quality is excellent, is conducive to differentiate and divide the work on stratum.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
